I agree. If everyone wasn't so effin' greedy they never would have gotten into this mess.Why do the people high up in companies have to make millions, or even billions when they can live just fine off of hundreds of thousands

Same reason we're not satisfied with being comfortable. No matter how much you have, if someone asks you how much you want the answer will be "just a little bit more".

You have a nice car, but you'd like something just a little nicer. Your house is nice but you'd like a little bigger yard, more bathrooms, a nicer garage, etc. Your job is ok but you'd like a little more vacation time, shorter hours, nicer desk/office/computer, etc...

No matter what people have, they're almost never satisfied. I think it's human nature to want to improve your position no matter how good the position is. If you're the best at something, you'll start looking at other areas to challenge yourself (such as moving up and down in weight classes in MMA). You know what I mean?
